The GEL-CUMULUS® 22 KNIT running shoe is an excellent choice for neutral runners that want a soft, flexible everyday trainer with a great fit. This version features a knit upper for a lifestyle appeal. The FLYTEFOAM® technology in the midsole is softer than the previous version to promote a pillowy ride. Under the heel where the foot first hits the ground has been redesigned to isolate impact while the new heel design's deeper forefoot flex grooves and softer midsole foam create a smoother ride. Lastly, a hard-wearing AHAR® rubber outsole compound has been placed in key contact areas to help the GEL-CUMULUS® 22 shoe stand up to a ton of miles.
